Connecting the Tape to the Float
Note Be sure to read this procedure before pro -
ceeding with this installation. Ensure you have
completed all previous steps from your installa -
tion checklist before proceeding.
1. Using the box that the tape came in, pull the tape
out like a measuring tape. This keeps the tape
from becoming twisted or kinked.
Figure 16: Feed the Tape into the Tank
2. At the elbow on the tank entry pipe, unroll one or
two turns of the perforated tape and start to feed it into the tank. If your installation is a
roof-reading application with the gauge head installed on the conduit on the roof, feed the
tape through the back of the gauge head first. Continue to unroll it several turns at a time
until it reaches the bottom of the tank. Let several more inches fall on the tank bottom.
3. Cut a 6-inch (152 mm) piece of tape from the end inside of the tank. Form a 'U' with this
piece of tape so there is no hole in the bottom portion of the 'U'. Do not kink.

4. Form a 'U' at the end of the perforated tape. Form it to match the 'U' piece previously
formed. Do not kink.
5. Install the gauge tape and 'U' piece to the tape connector with the tape clamps and screws
provided, making certain that the tape is not kinked or twisted.
6. Connect the grounding cable (A) to the tape connector (point B).
7. Attach the tape connector to the float.
8. Connect the grounding cable (A) to the float (point C).
